The Lowdown

Alright, Rusty here with the imperial version.

First off, don’t even bother paddling out Wednesday. That SW wind is onshore, the water’s a messy 73°F, and the combined swell energy is a weak 227 – it’s a washout. The anomaly on that water temp is only 1°F, so it’s pretty normal for this time of year.

Now, Thursday the 3rd is where it gets interesting. That morning window is the standout of the whole run. We’ve got a solid 7ft S swell with a decent 11-second period, strong energy readings of 1110, and a clean offshore ENE breeze at 12 mph. This is excellent surf for experienced surfers – it will be powerful and lined up. The afternoon drops off a bit with a cross-offshore wind and a 6ft swell, but still surfable.

Friday morning the 4th is a nice little bonus. The swell drops back to 4ft from the SSE, but with a 3 mph NNE breeze it’s glassy clean. Combined energy is moderate at 400. The afternoon gets a bit ordinary with cross-shore winds and a smaller 3ft wave.

Saturday the 5th is small and wet. Rain showers and a 2ft SSE swell with offshore wind early, but barely worth the paddle. Combined energy is only 122.

Sunday the 6th is a complete write-off – onshore wind, rain, and poor surf. Monday the 7th looks better again, with a 5ft S swell, cross-offshore breeze, and clean surface, but the period is a short 7 seconds. Combined energy is 295.

Now, the real long-range highlight lands on Tuesday the 8th. Morning and afternoon both score very good. Expect a 6ft to 5ft S swell with a 10-11 second period, combined energy around 647 to 595, and clean cross-offshore winds. This is the one to circle on your calendar.

Wednesday the 9th and Thursday the 10th both see a shift to E swell and some clean offshore winds – moderate energy around 480. The 5ft to 6ft waves are there, but the period is short (7-8 seconds). Friday the 11th is a hidden gem – glassy conditions in the morning with a 4ft E swell, then the afternoon jumps to 6ft ENE with a 9-second period and clean cross-offshore winds. Combined energy hits 634.

After that, from Saturday the 12th through Sunday the 13th, it drops right off. Poor surf, onshore wind, and combined energy below 150. Monday the 14th picks up again, but it’s tricky – a 3ft S swell with a very long 14-second period and cross-shore wind. The afternoon is bigger at 4ft but with the same problem.

The last few days, from the 15th to the 17th, are marginal. Clean conditions but small swell – mostly under 4ft. The 17th afternoon has a last little kick with a 4ft ENE swell and glassy conditions, combined energy 342.

So, the pick of the run: Jaconé on Thursday morning the 3rd with that big 7ft S swell, long period, and perfect offshore wind. Tuesday the 8th is your reliable backup.

Rusty.

Information about the Jaconé Surf forecast

The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.

Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
